Serena Williams always bring a bit of colour to the Australian Open, and now punters have got their first glimpse at what will light up Rod Laver Arena.

The tennis player, and part-time fashionista, is known for her colourful frocks and the 2012 iteration is no exception.

"I love this outfit because it makes your waist look small," the American superstar said.
